  Vulnerability Insight:

  USN-678-1 fixed a vulnerability in GnuTLS. The upstream patch introduced a
  regression when validating certain certificate chains that would report valid
  certificates as untrusted. This update fixes the problem.
  
  We apologize for the inconvenience.
  
  Original advisory details:
  
  Martin von Gagern discovered that GnuTLS did not properly verify certificate
  chains when the last certificate in the chain was self-signed. If a remote
  attacker were able to perform a man-in-the-middle attack, this flaw could be
  exploited to view sensitive information. (CVE-2008-4989)

  Affected Software/OS:
  gnutls12, gnutls13, gnutls26 regression on Ubuntu 6.06 LTS ,
  Ubuntu 7.10 ,
  Ubuntu 8.04 LTS ,
  Ubuntu 8.10

  Fix: Please Install the Updated Packages.
